Effect of scaling and root planing on serum C-reactive protein levels in patients with moderate to severe chronic periodontitis: a systematic review and Meta-analysis / 华西口腔医学杂志

OBJECTIVE@#To evaluate the effect of scaling and root planing (SRP) on serum C-reactive protein (CRP) levels in patients with moderate to severe chronic periodontitis.@*METHODS@#We searched the PubMed, Web of Science, EMBASE, Cochrane, CNKI, Wanfang, and VIP databases from the inception to July 8th, 2019. Two reviewers independently screened literature, extracted data, and evaluated the bias risk of included studies. Then, a meta-analysis was performed using RevMan 5.3 software.@*RESULTS@#A total of 13 randomized controlled clinical trials and 12 prospective clinical trials were included. Meta-analysis showed that serum CRP levels decreased at 2 and 3 months after SRP (P<0.05), and no significant difference in serum CRP levels was found at 6 months (P=0.49).@*CONCLUSIONS@#SRP can reduce serum CRP levels in systematically healthy patients with moderate to severe chronic periodontitis at 2 and 3 months after SRP.

Infection factors associated with neurodysplasia in early and moderately preterm infants / 中国当代儿科杂志

OBJECTIVE@#To investigate the infection factors associated with neurodysplasia in early and moderately preterm infants at a corrected age of 18 months.@*METHODS@#The preterm infants with a gestational age of 28 weeks to <34 weeks who were admitted to the neonatal intensive care unit and followed up at the outpatient service for high-risk preterm infants from June 2015 to December 2018 were enrolled as subjects. At a corrected age of 18 months, the revised Bayley Scales of Infant Development was used to evaluate neurodevelopment. Univariate and multivariate logistic regression analyses were used to investigate the infection factors affecting neurodevelopment.@*RESULTS@#A total of 138 early or moderately preterm infants were enrolled, among whom 59 had neurodysplasia at a corrected age of 18 months. The univariate logistic regression analysis showed that neurodysplasia was associated with late-onset infection, positive blood culture, and other systemic infections (P<0.05). The multivariate logistic regression analysis showed that late-onset infection was an independent risk factor for neurodysplasia (OR=1.510, 95%CI: 1.133-3.600, P<0.05).@*CONCLUSIONS@#Late-onset infection can increase the risk of neurodysplasia in early and moderately preterm infants.

Cranial measurement analysis of 3 406 infants aged 0 to 6 months in Chongqing / 国际儿科学杂志

Objective@#The incidence and distribution of positional deformities(PD)were studied by measuring cranial types of infants aged 0-6 months of 3 hospitals in Chongqing, and the recommended values of local PD were discussed.@*Methods@#Data of 3 406 infants with 0-6 months head size measurements were collected from the Second Affiliated Hospital of Army Military Medical University, Yongchuan Maternal and Child Health Care Hospital and Wanzhou Maternal and Child Health Care Hospital from September 1, 2017 to August 31, 2018, cranial vault asymmetry(CVA)and cranial index(CI)were calculated.According to different age groups, observe the distribution of cranial types, and use the current international common diagnostic criteria to understand the incidence of cranial abnormalities, and analyze the distribution of percentile values of CVA and CI in infants in Chongqing.@*Results@#According to the current international standard diagnosis of PD, the incidence of simple brachycephaly was the highest(39.9%)in the overall cranial abnormalities of infants, followed by brachycephaly with plagiocephaly was the second(36.1%), simple plagiocephaly was the lowest(6.9%), and normal cranial type only accounted for 17.1%.The detection rates of plagiocephaly(36.9%)and brachycephaly(67.0%)were the lowest in the 0-2 months group, and the highest in the 3-4 months group(47.3%/83.3%), and then decreased in the 5-6 months group(46.6%/80.2%).@*Conclusion@#The basic values of cranial type measurement of full-term infants in chongqing were significantly different from international reports, mainly due to the large CI value.The general international diagnosis standard for positional deformities do not conform to Chinese infants.We suggest that the reference value for positional deformities in this region is as follows: CVA≥0.4 cm is abnormal, of which 0.4 cm≤CVA<0.6 cm for mild plagiocephaly, 0.6 cm≤CVA<1.0 cm for moderate plagiocephaly, CVA≥1.0 cm for severe plagiocephaly; 82%≤CI≤91% is abnormal, of which 91%≤CI<94% for mild brachycephaly; 94% ≤CI<99% for moderate brachycephaly; CI≥ 99% for severe brachycephaly.CI≤82% is scaphocephaly.

Cranial measurement analysis of 3406 infants aged 0 to 6 months in Chongqing / 国际儿科学杂志

Objective The incidence and distribution of positional deformities ( PD) were studied by measuring cranial types of infants aged 0-6 months of 3 hospitals in Chongqing, and the recommended values of local PD were discussed. Methods Data of 3406 infants with 0-6 months head size measurements were col-lected from the Second Affiliated Hospital of Army Military Medical University, Yongchuan Maternal and Child Health Care Hospital and Wanzhou Maternal and Child Health Care Hospital from September 1, 2017 to August 31, 2018, cranial vault asymmetry ( CVA) and cranial index ( CI) were calculated. According to different age groups, observe the distribution of cranial types, and use the current international common diagnostic crite-ria to understand the incidence of cranial abnormalities, and analyze the distribution of percentile values of CVA and CI in infants in Chongqing. Results According to the current international standard diagnosis of PD, the incidence of simple brachycephaly was the highest ( 39. 9％) in the overall cranial abnormalities of infants, followed by brachycephaly with plagiocephaly was the second (36. 1％), simple plagiocephaly was the lowest (6. 9％), and normal cranial type only accounted for 17. 1％. The detection rates of plagiocephaly (36. 9％)and brachycephaly ( 67. 0％) were the lowest in the 0-2 months group, and the highest in the 3-4 months group (47. 3％/83. 3％), and then decreased in the 5-6 months group (46. 6％/80. 2％). Conclusion The basic values of cranial type measurement of full-term infants in chongqing were significantly different from inter-national reports, mainly due to the large CI value. The general international diagnosis standard for positional deformities do not conform to Chinese infants. We suggest that the reference value for positional deformities in this region is as follows: CVA≥0. 4 cm is abnormal, of which 0. 4 cm≤CVA<0. 6 cm for mild plagiocepha-ly, 0. 6 cm≤CVA<1. 0 cm for moderate plagiocephaly, CVA≥1. 0 cm for severe plagiocephaly; 82％≤CI≤91％ is abnormal, of which 91％≤CI <94％ for mild brachycephaly; 94％ ≤CI <99％ for moderate brachycephaly; CI≥99％ for severe brachycephaly. CI≤82％ is scaphocephaly.

Silencing HSV1 gD expression in cultured cells by RNA interference / 病毒学报

To explore the anti-HSV-1 effect of silencing gD gene expression by RNA interference, five 21-nucleotide duplex small interfering RNAs(siRNAs) targeting the HSV1 gD sequence were designed and the gD-EGFP fusion gene expression vector was constructed, then co-transfected into Vero cell, and screened the effective siRNA through analyzing the intensity of the EGFP fluorescence. Finally, the anti-HSV1 effect was confirmed by plaque reduction assay, real-time PCR and daughter virus titration of HSV1 infected Vero cells transfected with siRNAs. The study demonstrated that siRNAs could effectively and specifically inhibit gD gene expression in HSV1-infected cells, but only had a little effect on HSV1 infection, so taking gD as the target of siRNA against HSV1 needs further study.

Inverse PCR amplification of the complete major capsid protein gene of lymphocystis disease virus isolated from Rachycentron canadum and the phylogenetic analysis of the virus / 病毒学报

The major capsid protein of lymphocystis disease virus isolated from Rachycentron canadum (LCDV-rc) was amplified and analysed. The 457bp DNA core fragment was amplified with the degenerate primers designed according to the conserved sequences of MCP gene of iridoviruses, then the flaking sequences adjacent to the core region were amplified by inverse PCR, and the complete sequence was obtained by combining all of them. The open reading frame of the gene is 1380bp in length, encoding a putative protein of 459 aa with molecular weight 51.12 kD and pI 6.87. Constructing the phylogenetic tree for comparing the MCP amino acid of iridoviruses, the results indicated that LCDV-rc is most homologous to the other Lymphocystis viruses and all of them constitute a branch. Accordingly LCDV-rc is identified as Lymphocystivirus.
